1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background: Mucoepidermoid carcinoma (MEC) is a malignant tumor primarily composed of epidermoid, mucous, and intermediate cells. While it predominantly occurs in the salivary glands, MEC can also develop in the lungs, esophagus, breast, and thymus. Thymic MEC is rare, accounting for 2-3% of primary thymic malignancies. The primary clinical characteristic is incidental discovery in asymptomatic individuals. Due to the rarity of thymic MEC, much of the literature consists of case reports, and no standardized treatment protocol exists. Surgical resection is the primary treatment for MEC. Case Description: This report presents a case of thymic MEC identified incidentally during a routine physical examination in an asymptomatic patient. Chest computed tomography (CT) revealed a well-defined, rounded cystic-solid mass measuring approximately 61 mm × 32 mm in the right anterior mediastinum, with mild enhancement. Following comprehensive assessment to rule out surgical contraindications, the mass was resected. Postoperative pathology indicated a low-grade primary MEC, positive for epithelial membrane antigen (EMA), cytokeratin (CK)19, p63, CK7, cluster of differentiation (CD)5, and mucicarmine/Alcian blue (AB)-periodic acid-Schiff (PAS) staining. Ki-67 was ~5%, and fluorescence in situ hybridization (FISH) analysis confirmed mastermind-like transcriptional coactivator 2 ( Conclusions: This report details a rare case of thymic MEC. The diagnosis required pathology and molecular testing.
